Sponsorship:

This NATO Advanced Study Institute (ASI) is sponsored by the NATO Scientific and Environmental Affairs Division. Additional support is provided by the Biotechnology Division, National Institute of Standards and Technology, USA, the Danish Centre for Molecular Gerontology, Denmark, and the Turkish Society of Toxicology, Turkey.


  

INTRODUCTION

An Advanced Study Institute (ASI) is a high-level tutorial course of ten working days duration where a carefully defined subject is treated in depth by lecturers of international standing. ASIs contribute to dissemination of scientific knowledge and the formation of international scientific contacts. Presentations are made by the lecturers to about 60-80 ASI students who are mostly at the post-doctoral level. However, this does not exclude students who are about to obtain their doctoral degrees, and may also include other appropriately qualified senior scientists. Attendance at ASIs is open to all suitably qualified applicants irrespective of nationality. ASI students normally come from NATO countries; those from non-NATO countries may only receive financial support from the NATO grant if they are from NATO Cooperation Partner countries. ASI students are chosen by the organizing committee for their appropriate qualifications following their responses to advertisement of the ASI. Students are required to stay for the entire duration of the ASI to ensure full interaction.

NATO countries: Belgium, Canada, Denmark, France, Germany, Greece, Iceland, Italy, Luxembourg, Netherlands, Norway, Portugal, Spain, Turkey, United Kingdom, Unites States of America.

NATO Cooperation Partner countries: Albania, Armenia, Azerbaijan, Belarus, Bulgaria, Czech Republic, Estonia, Georgia, Hungary, Kazakhstan, Kyrgyzstan, Latvia, Lithuania, the former Republic of Macedonia, Moldova, Poland, Romania, Russia, Slovak Republic, Slovania, Tajikistan, Turkmenistan, Ukraine, Uzbekistan.


  

OBJECTIVES

Damage to DNA by both exogenous and endogenous sources is increasingly regarded as highly important in the initiation and progression of cancer and in the occurrence of other pathological events. DNA damage caused by reactive oxygen-derived species, also called oxidative DNA damage, is the most frequent type encountered by aerobic cells. Mechanistic studies of carcinogenesis indicate an important role of this type of damage to DNA. There is also strong evidence to support the role of oxidative DNA damage in the aging process.

DNA damage is opposed in vivo by repair systems. If not repaired, DNA damage may lead to detrimental biological consequences. Therefore, the repair of DNA damage is regarded as one of the essential events in all life forms. In recent years, the field of DNA repair flourished due to new findings on DNA repair mechanisms and the molecular basis of cancer. In 1994, DNA repair enzymes have been named Science magazine's Molecule of the Year.

There is an increasing awareness of the relevance of DNA damage and repair to human health. A detailed knowledge of mechanisms of DNA damage and repair, and how individual repair enzymes function may lead to manipulation of DNA repair in cells and ultimately to an increase of the resistance of human cells to DNA-damaging agents. Our knowledge in this field has increased vastly in recent years. The time is ripe to convene a NATO-ASI meeting of scientists of international standing from the fields of biochemistry, molecular biology, enzymology, biomedical science and radiation biology to analyze these questions in detail and to teach the student participants the basics and new developments of the field of DNA damage and repair. The lecturers will present and discuss the state-of-the-art knowledge and recent developments in this research field, and its pertinence to human health. In this meeting, we expect the interactions between the lecturers and participants to be synergistic and challenging, and to contribute greatly to dissemination of scientific knowledge and the formation of international scientific collaborations.
